This is an implementation of RFC #51: https://github.com/bevyengine/rfcs/blob/main/rfcs/51-animation-composition.md Note that the implementation strategy is different from the one outlined in that RFC, because two-phase animation has now landed. # Objective Bevy needs animation blending. The RFC for this is [RFC 51]. ## Solution This is an implementation of the RFC. Note that the implementation strategy is different from the one outlined there, because two-phase animation has now landed. This is just a draft to get the conversation started. Currently we're missing a few things: - [x] A fully-fleshed-out mechanism for transitions - [x] A serialization format for `AnimationGraph`s - [x] Examples are broken, other than `animated_fox` - [x] Documentation --- ## Changelog ### Added * The `AnimationPlayer` has been reworked to support blending multiple animations together through an `AnimationGraph`, and as such will no longer function unless a `Handle<AnimationGraph>` has been added to the entity containing the player. See [RFC 51] for more details. * Transition functionality has moved from the `AnimationPlayer` to a new component, `AnimationTransitions`, which works in tandem with the `AnimationGraph`. ## Migration Guide * `AnimationPlayer`s can no longer play animations by themselves and need to be paired with a `Handle<AnimationGraph>`. Code that was using `AnimationPlayer` to play animations will need to create an `AnimationGraph` asset first, add a node for the clip (or clips) you want to play, and then supply the index of that node to the `AnimationPlayer`'s `play` method. * The `AnimationPlayer::play_with_transition()` method has been removed and replaced with the `AnimationTransitions` component. If you were previously using `AnimationPlayer::play_with_transition()`, add all animations that you were playing to the `AnimationGraph`, and create an `AnimationTransitions` component to manage the blending between them.
